The islands lie c.13 km south-east of St Eustatius, 67 km west of Antigua and 25 km north-west of Redonda (to Antigua and Barbuda). St Kitts is the larger island (168 km2) supporting c.75% of the population, and is separated from Nevis (93 km2) by a shallow 3-km channel called “the Narrows”. Nevis is south-east of St Kitts. The islands constitute the smallest nation in the Americas in terms of both area and population, and were also DPRQJWKHÀUVWLVODQGVLQWKH&DULEEHDQWREHVHWWOHGE\(XURSHDQV Both islands are volcanic in origin. The northern end of St Kitts is dominated by the dormant volcano Mount Liamunga (1156 m) which is cloaked in tropical moist forest at higher elevations while the lower slopes have EHHQFOHDUHGIRUDJULFXOWXUH VXJDUFDQHSURGXFWLRQHQGHGLQ 6WUHDPVÁRZGRZQWKHQXPHURXVJKDXWVRQ the sides of the volcano. The northern coastline of St Kitts is primarily cliffs of up to 15 m high. The south-east of the island comprises low hills supporting dry thorn-forest along a tapering peninsula used for grazing livestock and for tourism development. The southern coastline is characterized by sandy or rocky shores with saline coastal ponds. Nevis is a conical-shaped island formed by an extinct volcano that rises to 985 m at Nevis Peak, and is similarly vegetated to northern St Kitts. The island is fringed on three sides by long sandy beaches, and protected by (intermittent) fringing coral reefs. St Kitts and Nevis have a tropical maritime climate. Average annual rainfall is 1300 mm although low-lying areas can receive as little as 200 mm and it can reach over 3800 mm on the volca- noes (up to 6000 mm has been recorded). Most of the precipitation arrives during hurricane season in late summer and fall. Modern land use (on St Kitts) includes agricultural plantations in the lowlands, local market agriculture, WRXULVPGHYHORSPHQW HVSHFLDOO\IURP%DVVHWHUUHWR)ULJDWH%D\DQGWKH6RXWKHDVW3HQLQVXOD ÀVKLQJDQGOLJKW manufacturing. On St Kitts the Central Forest Reserve was created as a result of the Forestry Ordinance (1904) which legislates for the protection of areas above 300 m. This ordinance was enacted to prevent further deforestation (at the hands of the sugar- cane industry) and thereby also protect soil and water sources. The Wild Birds Protection Ordinance (1913) prohibits the KXQWLQJRIVSHFLHVRIELUGDQGHVWDEOLVKHGDUHJXODWHGKXQWLQJVHDVRQIRUDQRWKHUQLQHVSHFLHVUHÁHFWLQJWKHQXPEHU of bird species known on the island at this time. The National Conservation and Environment Protection Act (1987) legislates for further protection of c.90 species. However, the extent to which these laws are enforced is unknown.

(1997) provides data from their research on St Kitts in the 1970s and 1980s. Birds have been documented informally for many years on Nevis (e.g. through the maintenance and provision of birding lists for visitors). The NGO Nevis Historical and Conservation Society is active on the island, especially with education and awareness efforts and community conservation action. 1 This directory only includes global IBAs, for regional IBAs using “B” or Caribbean criteria, see BirdLife International (2008). Much of St Kitts was converted (by the British) to agricultural land domi- and terns through trampling. The government has recently undertaken a nated by sugarcane.
